To alliwhom "it may concern;

Be it known that l, lNILLIAM J. BAKER,

residing at Newport, inthe county of Campor bolts.

Specifically my inventionembodies an imoroved construction of framehaving interoclring parts for the screen clamping portion, so arrangedthat the screen can be readily removed from the frame for replacemeritwhen worn.

In, its more subordinate nature, the in vent-ion embodies certain novelfeatures of construction, and detailed arrangement of parts, all ofwhich will. be first described, then be specifically pointed out in theappended claims, and illustrated in the accor panying drawings, in whichFigure 1 is a front elevation of a screen embodying one form'of myinvention, showing how the same maybe secured in the Window frame. -Fi2, is a horizontal section von the line 22 oil Fig. 1. Figs. 3 to '16inclusive are detail views of various modifications hereinafterspecifically referred to.

Referring now to the accompanying drawings, in which like letters andnumerals of retterence indicate-like parts in all of the figures, itwillbe seen that the screen A comprises a sheet metal frame consisting ofthe top frame section a-and the bottom frame section 7), both of whichmay be of the same cross sectional type, or form, while the sidesections 0 maybe of-the same sectional -form as the too and bottomsections a and b, or

they mayliave a different sectional form and prcvidedwith integralguides, when 1t is desired to use the metal screen in a Window framehaving wooden slide bars B 1n place of metal slides.

Q designates fixed slide engaging members carried by one side section cto engage the slide bars B while the other side sectionc car-Specification of Letters Patent.

ries sliding lock members D to engage the slide bars B, the sliding lockmembers D being capable of withdrawal from engagement with the slidebars l) to permit of the removal of the screen. The screen also includesa wire screen section V? which is held by the sheet metal frame sectionsa, b and c.

The frame sections, a, l) and c ma be of various forms in cross sectionand I have illustrated numerous modifications of my improved form ofscreen in the accompanying drawings by reference to which it will beseen tlin the form shown in Fig. 3,. the

screen f1 ame section consists of a list bottom I or base 1 withupwardly extending integrally formed sides 2 and 3 arranged parallel toone another and spaced apart, the upper ends of which are bent as 2 and3, one of said ends 2 overlapping the other 3 as shown. Each of theoverlapping ends 2, 3* have their edgesbent back upon themselves as at3* and 2 res actively, the edges 2* and 3 being bent to he between theends 2 and 3 respectively, as clearly shown in the drawings.

The screen wire W is clamped between the ends 2 and 3 and the edges 3and 2 and the side wall2 of the frame section, as clearly shown in thedrawings, giving the screen wire, as it were, an S-shaped bend Where itpasses between the ends 2 and 3 of the sheet metal frame section. Itwill also .be seen that by this construction the edges 2 3 liesubstantially in the same plane when the screen is clamped in the frameand thus prevent the screen drawing out, and furthermore keep the sides2 and 3 in parallel relation.

Instead of making the screen sections in one iece, as shown in Fig. 3,the same effect can e obtained by constructing the sections as shown inFig. 4, wherein the screen section is formed of two parts, the base 1being formed partly on one part and partly on the other, and consists ofthe portion 1 bent at right angles to the side 2 and toward the otherside 3 and given a slightly curved. form to cooperate with the baseportion 1 that is formed with the side 3 and extends toward the side 2,the edge of the base portion 1 being bent under, as at 1, to cooperatewith the.

base portion l and form, as it were, a rigid structure. g I In Fig. 5, Ihave shown a further modificain place and by reason of the folded orbent this-{form of my invention the bent over edge 1 into two differentplanes, one portion 1 of 5 gether into a rigid structure.

' the drawings and in this form where the side form shown in Fig. 4:,but the base 1 in this from the side 3, the edges of which are bent theedges 3"'2 of the screen clamping por- "tion of the frame, and when thisform s tion duly performed, the bottom-1 is bent tion of my invention,and in this form the screen section 1s made in two pieces, as in theform consists of flat base portions 1 bent over at right angles from theside '2 and the fiat base portion 1 bent over at right angles over as at1 and l, in a manner similar to used, it will be seen, when the twoparts are placed togetherthey will, owing to the resiliency of themetal, spring lock themselves over edges.1 1- and 3' 2 the twoparts willbe prevented from coming apart.

Fig. 6, shows the same general idea disclosed in Fig. 5, with theexception that in 1 is omitted, and in order to have its func-' upwardlyto form a bead 1 which corre-' sponds to the end 1 of Fig. 5-.

In Fig. 7, I have shown the same form of screen shown in 6, but .adaptedfor use as the side screen section '6, of the-screen, and in .thisforman integral guide l is projected downwardly from the member 1 and thisguide may haveits end 1 bent back to form a stiffening portion, as maybe found desirable.

Fig.8 shows essentially the same idea disclosed in Fig; 7 with the.exception that in this form the bent over edge 1 is omitted and itsfunction is performed by providing the bottom 1 with a bead 1 to bringthe bottom apping, as before, but each of these bottom portions 1 1."areprovided with a longitudmal corrugation or bead 1 and 1 which are i 1adapted to register with one another and thus lock the two bottomportions 1 1 to- Fig. 11 illustrates the same form shown in Fig. 10,with an integrally formed guide 1 formed with the bottom portion 1 Fig.12 illustrates a further modification of the clamping surfaces of theframe section. ,In this form the upper ends of the sides 2 & 3 are bentinwardly toward one an other to lie in arallel planes, as at 3 2 in amanner similh-r to that shown inFig. .3 of

3 and ends 3 meet an inwardly depressed corrugation 3 is provided tocooperate with.

a bead 2 correspondinglyformed on'lthe edge of the end 2'. v

Fig. 13 shows another modlhcatlon of the general type disclosed in Fig.3, of the drawings, but in this form the bent over edge 3 is omitted and1n lieu thereof its function is performed by bending up the edge 3 ofthe end ,3 of the side 3 thereof so as to form a channel for the screenof substantially an S-shape similarly to the mannerdisclosed' in Fig. 3,but in this form the base 1 is formedintegral with the sides 2 and 3.

Fig. 14 illustrates the same formshownin Fig. 13 with the base lforinedof two members, one of which 1, is formed with the side 2 and the other1 is formed with the side 3, the two members over-lapping andinterlocking, as shown.

F ig. 15 shows another modification of' my invention which is.substantially the same as Fig. 12, except that both the top and bottomportions of the screen sections are formed alike and in this form alsothe fixed guide 1 may be provided, or omitted, as the case may be.

From the foregoing, it will be seen that in each from of my inventionthe screen frame section comprises a base '1, parallel sides 2 and 3 anda top 5, formed by bending over the upper ends of the sides 2 and 3, ashereinbefore described, and in some cases the bottom is made by bendingover the lower ends of the sides 2 and 3 as at 1 -1 thus forming what isknown in the art as a twopiece screen. When I refer to the upper ends ofthe sides 2 and 3 of the screen section I intend that term to be readinconnection with the parts in the position shown in Sheet 2 of thedrawings containing Figs. 3 to 16, inclusive, and to include within itsdefinition the parts ,2 --3 of the sides 2 and 3, and the equivalents ofsuch parts 2 and 2 the expression upper ends being a relative term usedin order to clearly define the features of applicant's invention.

From the foregoing description taken in connection with the accom anyingdrawings, 1t 1s ,thought the -comp ete constructlon, operation and manyadvantages of my mvention will be readily understood by those skilled inthe art to which the invention appertains, andin order to release thescreen cloth from the frame, it is only necessary to insert a screwdriver, or other'similar tool, between the ends 3 and 2 and pry the sameapart, thus permitting the sides 2 and 3 to be pried apart out 'ofparallelism, or when the form of the general type shown in Fig. 5

is used, by prying apart t e ends 3 and 2 which form the top the parthaving the side 3 may be entirely removed.v

Any suitable corner braces nlay be provided for'the screen, such forinstance, as

shown in Fig. 16, of the drawings, by refer-- over end of one sideportion projecting toward that of the other side portion, one of saidends overlapping the other, said ends being provided with portions lvingin the same plane and other portions lying in different parallel planes,and a wire screen member clamped by said frame section, substantially asshown and described.
